These helices are enclosed in` and secured to the cover of thecasc by a casing on- Btructed of tin, in, on the outside circumference, und on the inner circumferencmby a ring, N, pf plat-ina, joined to the tin, and to the cover of themcase. '.lhis casing may be constructed of but one kind ot' metal, or of any other suitable material, and the special purpose of .which is to protect thc coils from contact with the moisture that may arise from the solution used. in the battery.

The two helices are combined into one in the following manner: The .inner c nd ot' the 'rst prime oil AEl", iigs. 7 and 8;, (also indicated by the dotted lines in 2,) is connected to the adjustingscrcw a of the armature U', fig. 2,land the outer end to the inner end of the second prime `coil T; also the outer end of the second i pri-mecoil T is attached'to the e'onneting-post` f, which connects with tho 'zinc ornegative .pole of the battery.

One end of the wire, b', coiled around the magnet U, is fastened tothe same, z'. o., te the core of the magnet, and the other to the hitching-post g, which connects with the copper or positivo pole of thc battery by means of the wire y. The inner fend ofthe induction-coil m,surrounded by the prime coil above described, and

The outer end forms the negative, and is attaichedtothe bitching-post f.

Theso two magnets vare connected to cach other by a bridge, W,undA by which they aremoved together upward and downward withim the helices by an adjusting-somma, projected above the cover of thel battery, By this means are regulated the quantity and intensity of the interruptedelectro-current,
